Melania Trump wears $7,236 red gown from Meghan Markle's go-to designer for final state visit dinner

Proving she’s well-versed in the art of diplomatic dressing, Melania Trump flew the American flag in a red cape-sleeved gown at Tuesday’s final state visit dinner in London.

It’s interesting to note that the dress is by one of Meghan Markle’s favorite designers: Clare Waight Keller for Givenchy, who designed the duchess’s 2018 wedding gown as well as other standout looks. That’s certainly one way to strengthen sartorial ties with the royal family.

The 49-year-old chose to accessorize the $7,236 sequinned gown, which is surprisingly still available to shop online, with co-ordinating shoes and loose curls.

The evening’s reciprocal dinner at Winfield House saw Donald Trump play host at the residence of U.S. ambassador Woody Johnson, with Prince Charles and the Duchess of Cornwall as guests of honor.

Prince Charles chose a tuxedo for the event while the Duchess of Cornwall opted for a cream-hued gown with matching pearls.

The first lady has continued to pull out all the fashion stops during the couple’s U.K. trip.

On Monday night, she chose a Christian Dior number for the Buckingham Palace banquet. She finished the ensemble with elbow-length gloves and a chic up-do.

The fresh-from-the-runway look set the sartorial tone for the evening with the likes of the queen, Kate Middleton and the Duchess of Cornwall also wearing the neutral shade.

Wednesday is the Trumps’s final day in the U.K. with the couple expected to visit Southsea Common in Portsmouth for the 75th anniversary of the D-Day landings.

They will be joined by the queen and Prince Charles for a national commemorative event before flying back to the United States.
